Descriptive Problem Summary:

I have a project demonstrating an anomalous output from vis-y. I'm getting correct vis-x values, but incorrect vis-y values. In this case, it's returning vis-y values that are around -1000px, when the icon-y values in the params list are around 20.

Run the sample project sent via DM 8/11/2023 @ 10:28pm. Click and drag on the title bar of the UI window in the center of the screen. It will disappear, because the drag action is being fed insane values from params.

However, if you open the world.log, you'll see the param string of initiating moment showing the invalid vis-y.

Code for this series of actions can be found in widgets/winframe/window.dm, starting around line 51.
